Blasting into Frieza with all I was worth, I barely managed to protect Krillin in his grip as we went deeper and deeper into the depths of the planet. Eventually, Frieza lost his hold on Krillin and the poor guy, unconscious by this point, was lost in a cavity in the tunnel that our grapple had dug, but neither of us were done yet.
"HYAAH!" With a scream, which of us it came from, I wasn't sure, the rocks around us seemed to vanish, destroyed utterly by the energy as Frieza and I powered up to supernatural proportions. Frieza's limbs began to bulge and the tip of his tail regrew. If I were to guess, I'd say that he was using about 75% of his full power by this point, or around 90 million. In response, my own power level, bolstered by the true, fully controlled Silver mode, grew. Doubled, then tripled in response to Frieza's power.
'Mistress, the energy coming from you two is affecting the planet's inner core. The other girls have it stabilized for now., but the planet's magnetic field, and future spin rate have been slightly affected.' Shay reported as our powers peaked. Basically what that meant was that the planet's gravity and atmosphere were going to fluctuate over the course of the next few centuries if nothing was done to fix it. Another way of putting it was that the planet was now going to go through three or four different extinction level events due to this fight. Chances of survivors on the surface were now close to zero. Now, the Namekians would need to be relocated, one way or another, or our promise to Guru would go unfulfilled.
That was fine, though. Nine-tenths of the theoretical Frieza battles ended the same way, after all. Frieza was a horribly sore loser.
"OOOOHHH..." I began charging up for the strongest Supreme Wave I'd ever done outside of the Core. In the cavern beside me, Frieza did the same thing.
"SEE MY TRUE POWER AND FALTER IN TERROR! DEATH WAVE!"
"HAAAA!!!" As I felt Shay's presence leave my jacket to set up the next portion of my plan, Frieza and I unleashed our energy waves at the exact same time, but upon collision, something strange happened. The energy waves began melding. The core of my Supreme Wave began eating into Frieza's Death Wave, while the uniform density of his Death Wave began to meld with the cloud around that core as a result.
In moments, the energy waves between the two of us had perfectly melded into a red and silver beam, and we were both forced to move out of the way as the energy blasted back at both of us. Unfortunately, my body didn't manage to get out of the way in time, and my right arm was disintegrated right out of its socket, along with the jacket sleeve covering it. Frieza didn't get off scot-free either, though, as the core of the wave blasted clear through his left shoulder.
Unfortunately, while my right arm was completely gone because of the hit, Frieza could still use his left perfectly well. On top of that...
'Mistress. The planet's inner core was impacted by the core of your Supreme Wave. Fifteen minutes until the planet explodes, but we will keep an eye on it and adjust as necessary.'
...
After a moment of calmness, Goku felt the energies erupt underground once again. Both had been clearly weakened by the explosions and energy waves, but the one that didn't belong to Frieza was clearly far worse off. The energies fought for a single moment, but Frieza was absolutely dominating now, in a clearly different league than anything before. A league that Goku couldn't match, even with a Kaio-ken times 25. Finally, Frieza and his unknown assailant began speeding toward the planet's surface once more, erupting out of it via the same hole, moving faster than even Goku could see.
But their quick fight, despite its intensity, only lasted for a few moments. Soon, both stilled. "You've been a pain."
"Can't get there in time!" Goku shouted as he blasted toward Frieza, who was holding me by the hair. I looked like a wreck. My right arm and jacket were completely gone, and my left shoulder had been dislocated by Frieza during our short fight aboveground. Honestly, the pain was the only thing keeping me conscious at this point, but I still channeled all of the energy I could into my mouth as I glared at Frieza, knowing that even if it hit, I'd not even scratch him anymore.
But it never hit. With his muttering of 'You've been a pain,' Frieza tossed me up into the sky as high as he possibly could. For a moment, I could feel the weightlessness and oxygen-less atmosphere of space. Then, he shot a powerful blast of energy at my body, disintegrating it on contact.
"HANNA!!!! YOU-YOU EVIL BASTARD!!! I'LL NEVER FORGIVE YOU FOR THIS!!!!" Seeing my death, Goku howled as he flew toward Frieza in a flash of blinding light. Unlike his transformation in canon, this Super Saiyan transformation happened in a flash. Suddenly, Frieza found himself being beaten silly by something that his eyes could barely even register, even at 75% of his maximum power.
...
"So Mistress is dead."
"Yup."
"So we'll torture that Frieza bastard's soul for all of eternity, once Mistress has lost interest in him?"
"Duh."
"Does Frieza have any other purpose to serve, now that Goku's become a Super Saiyan like Mistress intended?"
"He's to be killed. Then tortured. Since he's garnered so much hatred from the girls here, we're thinking of using him as a punching bag here in the Core, for the rest of eternity. The Grand Minister has already given his approval, so long as Frieza dies first. One missing soul isn't that big of a deal." Chelsea relayed the current plan to the other girls watching from the well. Almost all of them had unconsciously powered into their divine forms upon seeing me die, and the energy in the room would literally have suffocated someone with powers even slightly less than that of a literal deity.
Naturally, the girls all nodded along with the horrible things that Chelsea was saying they'd do to Frieza once he died, eager to get their hands on the tyrant.
So Hanna's dead. What will happen next, and why hasn't she automatically returned in her unsealed form? Questions, questions...
